as_point1d

as_point1d.numeric

as_point1d.character

as_point1d.Coord1D

as_point1d.Point1D

<code>as_point1d()</code> casts to a Point1D object.

Dilate, permute, project, reflect, rotate, shear, and translate 2D and 3D points.  Supports parallel projections including oblique projections such as the cabinet projection as well as axonometric projections such as the isometric projection.  Use 'grid's "affine transformation" feature to render illustrated flat surfaces.
